Abstract
The invention relates to silane compounds having the general formula (I): SiR1n(R2)4-n (I), as defined herein, to a method for preparing the silane compounds and use thereof as crosslinker or as adhesion promoter and to a curable composition comprising a reaction product of the at least one silane compound, at least one polyorganosiloxane, and at least one catalyst, and use thereof.
Claims16
A silane compound having the general formula (I)
- SiR1n(R2)4-n (I)
- wherein each R1 is same or different and is, independently of one another, selected from radicals having the general formula (II)
- —OCH(CH2COOR3)COXR3 (II)
- wherein
- X is O or N, and
- each R3 is same or different and is, independently of one another, selected from the group consisting of substituted or unsubstituted, linear or branched alkyl radicals having from 1 to 22 carbon atoms, aryl radicals having from 6 to 16 carbon atoms, and cycloalkyl radicals having from 5 to 27 carbon atoms, where R3 may contain at least one heteroatom selected from O, N, Sand/or Si;
- each R2 is same or different and is, independently of one another, selected from the group consisting of a hydrogen atom, a hydroxyl group, substituted or unsubstituted monovalent hydrocarbon radicals having from 1 to 18 carbon atoms, and alkoxy radicals having from 1 to 8 carbon atoms;
- and
- n is 2, 3, or 4.
